No Drawing.

To all whom it may concern:

Be it known that I, MATHIAS PIER, a subject of the German Emperor, residing at Berlin, Germany, have invented a new and useful Process for the Manufacture of Ammonia from its Elements; and I do hereby declare the following to be a full, clear, and

cleaned product is mixed with an -oxid or carbonate of the alkali group or alkaline earth group. The contact mass is dried in a nitrogen-hydrogen current and then it shows preeminent catalytic qualities in the contact furnace.

'If rhodium chlorid is prepared in the above mentioned manner, it acts in exactly the same manner and becomes a preeminent Specification of Letters Patent.

Patented Oct. 19, 1915.

catalytic agent for the generation of arm monia.

1. A process for the manufacture of ammonia from its elements, said process consisting in imiting the elements to be combined by bringing them into contact with catalytic agents of the platinum group carried by a carrier having therein a combination of an alkali.

2. A process for the manufacture of ammonia from its elements, said process consisting in uniting the elements to be combined by bringing them into contact with catalytic agents containing rhodium.

3. A rocess for the manufacture of am monia f i'om its elements, said process consisting in uniting the elements to be combined by bringing them into contact with catalytic agents containing rhodium carried by a carrier having therein a substance con- .taining an alkali.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
